[PATCH 0/2] test: py: Fix unit test error with ASan

[Laurent Pinchart]

Hello,

This small patch series fixes a Python bindings unit test error when
using ASan. The issue seems to be caused by a bug in ASan, as reported
in https://github.com/google/sanitizers/issues/934, which is triggered
when dynamically loading a .so module in conjunction with a libasan
implementation linked with --as-needed. This causes a failure to
properly handle exceptions.

Patch 1/2 is a small improvement for the Python unit test meson.build
file, to prepare for patch 2/2 that then works around the issue by
LD_PRELOAD'ing the C++ standard library.

The series doesn't break CI
(https://gitlab.freedesktop.org/camera/libcamera/-/pipelines/1304028)
and fixes the issue on my machine with gcc 9 to 14, using libstdc++.
clang with libc++ is still broken, waiting for a volunteer to fix it :-)
